jQuery

I am doing exactly as the video.When I log in the preventDefault is not turned of.The code is exactly as in the video but get a different result in console.What is wrong with my code?I practise on my own project. // Problem: When clicking on image,go to a dead end // Solution: Create an overlay with the large image - ligthbox

// Plan: // 1.Capture the click event on a link to an image $("#imageGallery a").click(function(event) { event.preventDefault(); var href = $(this).attr("href"); console.log(href); // 1.1 Show the overlay // 1.2 Update overlay with the image linked in the link // 1.3 Get child attribute and set caption - can use the href attribute // 2. Add an overlay }) // 2.1 An image // 2.2 A caption ? // 3. When overlay is clicked // 3.1 Hide the overlay
